A. B. What is the difference between "1", 1, 11, and 1+0i? If we were to create an atomic vector using the command of"1", 1, 11, 1+0i), how will this vector be saved in the environment? Character? Numeric? Integer? Logical? And why? C. What does the command 10:0 generate? What about seg len(20)? And finally, what about seg along(10:0)? D. In the screenshot below, what does [127] mean?

Create a matrix whose elements are as shown, and name this matrix My Mat (,1) 0,2] [3] [,4) 0,5) [1.] 1.000 1.275 1.550 1.825 2.100 [2.] 1.855 1.330 1.605 1.880 2.155 [3,] 1.110 1.385 1.660 1.935 2.210 [4.] 1.165 1.440 1.715 1.998 2.265 [5] 1.220 1.495 1.770 2.645 2.320 F. Using the matrix created in (5), what command do we issue to change the [1,). [2.), ---, (5,1 (row labels) to "Row 1", "Row 2", ..., "Row 5?" In addition, what command do we use to change the column labels to "Column 1", ., "Column 5?" G. Create a dataframe that has the following variables: Name, Age, Birthday, Height (in cm), Weight (in kg) using yourself as the only observation. Name this data frame My Df. Example shown below Name Age Birthday Height Weight 1 Jan Gil 18 ox-XX-19XX 172 60 H. Insert your calculated BMI in My Df using the command My Df[1,"BMI"]
